Specification of Letters Patent.

Patented May 8, rear.

Application filed. May 4, 1915, Serial No. 25,796. Renewed March 21,1917. serial lto. 156,459.

To all whom it may concern:

Be it known that we, OLE C. NUUBsoN, a subject of the King of Norway,and JoHAN A. NUBSON, a citizen of the United States, residing at Duluth,in the county of St. Louis and State of Minnesota, have invented a newand useful Dough-Sheeting Machine, of which the following is aspecification.

This invention has reference to dough sheetin machines, and is designedto form dough 1nt0 sheets of suitable thickness and to cut the sheetsinto lengths suitable for baking into a form commercially known as fiatbread, and especially in connection with a machine such as shown anddescribed in Reissue Letters Patent No. 13,808, granted to one of us,namely, Ole C. Nuubson, on

- series beingan upright series, so that the dough in passing betweenthe pairs of rollers of the series travels in a downward direction.Provision is made for supporting the dough sheet in its travel from onepair of the series to the next lower pair so that the weight of thetraveling sheet is not sufficient to rupture the dough. -Moreover,provision is also made for preventing the dough from sticking to therollers and for applying flour to opposite faces of the dough to furtheraid in preventing sticking.

The dough in its passage through the series of rollers becomes reducedin thickness to the desired extent and is thereupon directed to atraveling apron which carries it to a table which may be arrangedhorizontally. After leaving the rollers and before reaching the tablethe sheet of dough is subjected to the action of trimming means, usuallyin the form of rotating cutters whereby the dough sheet is made of therequisite width with the side edges parallel. On reaching the table thetraveling dough sheet is periodically subjected to a severing meanswhereby the sheet is cut into desired lengths appropriate for the bakingmachine. and after the dough sheet is thus severed it may be readilypicked up by a suitable tool allowing the transportation of the sheet tothe baking machine and its deposition thereon.

The invention will be best understood from a consideration of thefollowing detailed description, taken in connection with theaccompanying drawings forming part of this specification, with thefurther understanding that while the drawings show a practical form ofthe invention, the latter is not confined to any strict conformity withthe showing of the drawings, but may be changed and modified so long assuch changes and modifications mark no material departure from thesalient features of the invention.

Fig. 7 is a perspective view of a dough lifting device.

Fig. 8 is a view of a driving mechanism for the rollers which mayreplace that shown in Fig. 1 and associated figures.

Fig. 9 is still another form of roller-driving mechanism from that shownin Fig. 8.

Referring to the drawings there is shown a frame composed of uprights orposts 1 and connecting members 2 and other connecting members 3 for theposts prolonged to one side of the connected posts and supported at theend remote from the posts by legs 4 and suitably stifiened by braces 5,6, the braces 6 being connected at one end to the beams 5 and at theother end to certain of the posts 1 at a high point thereon.

The posts 1 provide an upright frame, near the top of which there isjournaled a shaft 7 carrying tight and loose pulleys 8, 9,

whereby power may be applied to the shaft 5 ticular showing of thedrawings the shaft 7 is continued across the upright frame to the sidethereof remote from the pulleys 8 mesh with another gear wheel 11 on ashaft and provided exterior to said frame on the end of the shaft 12remote'from the gear wheel 11 with a bevel pinion 13.

Arranged alongside of the upright frame in spaced-relation to that sideof the frame remote from he pulleys 8 and 9 is an upright shaft 14'having a step bearing 15 at .the lower end and provided at the upper endwith a journal support 16, and above the latter with a bevel gear 17 ain mesh with the pinion 13, whereby the shaft 14 receives power from thedrive pulley 8.

At appropriate points .on'the shaft 14 are friction wheels 17, 18 and19, respectively. The friction wheel 17 is relatively small, thefriction wheel 18 is larger, and the friction wheel 19 is the largest ofthe three. The three friction wheels 17, 18 and 19 are disposed alongtheshaft 14tin the order named with the smaller friction wheel at a higherpoint than the larger friction wheel. At a still lower point the shaft14 carries another friction wheel 20 to which reference will hereinafterbe made.

At appropriate points along the'shaft 14 it is engaged by bearing blocks21 held to one of the uprights 1 by brackets 22. The

blocks 21 are designed to resist any side thrust tending to force theshaft 14 away from the upright frame.

Mounted in journal bearings 23, 24 at appropriate points alongthe-upright frame, and particularly where capable of. support by thecross pieces 'or beams 2 and 3, are transverse shafts 25, 26 and 27carriedby the journal bearings 23 and other transverse shafts 28, 29 and30 carried by the-journal bearings 24. The shafts 25, 26 and 27 carryrollers 31, 32 and 33, respectively, and the shafts 28, 29 and 30 carrysimilar. rollers 34, 35 and 36, respectively.

The journal bearings 23 may be fixed, while the journal bearings 24 areadjusted toward and from the journal-bearings 23 by means of adjustingscrews 37 threaded through appropriate brackets .38 on the beams 2 and3, whereby the rollers 34, 35

and 36 may be adjusted toward and from the rollers 31, 32 and 33,respectively, for a purpose whichwill hereinafter appear.

At that end of the shaft 25 toward the shaft 14 there is secured afriction disk 39 andthe shafts 26 and 27 carry friction disks I 40 and41, respectively, these disks varying 05 in size in inverse proportionto the differ- 12 suitably journaled in the upright frame ences in sizeof the friction rollers 17, 18 and 19,,and the friction disks are indriving relation. to the friction wheels. 7

' The rollers 31, 32 and 33 are each connected to the-companion rollers34, 35 and 36 by intermeshing gear wheels 42 and 43,

' so that the rollers of each pair rotate'oppoand 9, and there carries agear wheel 10 iny site'ly at the same speed, although because of thedifferent sizes of the friction wheelsand companion friction disks of.the different a slower speed than the next lower pair of rollers 32 and35, while the lowest pair of.

rollers 33 and 36' have the highest speed of rotatlon of the series.This difference of speed of rotation as to the diflerent pairs ofrollers of the series is for a purpose which will hereinafter appear.-

The rollers of the upright series of rollers are located one above theother, and below the series and mounted in the upright frame to one sideof the upright center line of the 891185 of rollers is a shaft 44 havingjournal bearings 45 on suitable connectors or beams 2 joining theupright beams 1 and located near the bottom ends of these beams. Theshaft 44 carries a drum 46- between the journal bearings and is extendedto one side of the upright frame where it carries a fric tion disk 47 infrictional engagement with the friction wheel 20, so that the shaft; 44receives motion from the haft14.

Mounted on the beams 3 where extended awaysfrom the upright frame is atable 48 over which travels one run of an endless apron 49. This apronis carried about the drum 46 which is located at a lower point than thetable 48 and from thence the apron passes about a supporting anddirectionchanging) roller 48 mounted in bearings 50 carried y the beams3, from which roller the apron passes over another roller 51 close toone end of the table 48 and over still another roller 52 at the otherend of the table, the apron returning to the drum 46 beneath the table48 and the beams 3, the I return or' lower run of the apron passing overa supporting rollerv 53 supported in ournal bearings 54 on hangers 55pivoted to and depending from the beams 3 by pivots 56. The hangers 55have side extensions 57 through which are threaded set 1 naeaaei securedto a respective post 1 by a bolt or other convenient means. On oppositesides of the bolt 65 each rocker arm 64 has threaded through it a setscrew 66.

Extending lengthwise of and below each roller 31, 32, 34 and 35 is anelongated rotary brush 67 carried by a shaft 68 having appropriatejournal bearings in the upright frame. At the lower end of each spoutcontinuation 62, such spout in operative position slanting downwardlytoward the brush 67, is a closure 69 of wire or other screen cloth whichby adjustment of the screws 66 may be brought into a desired relation tothe brush 67, which latter may have tufts 7 0 of bristles.

Extending transversely of each roller 31, 32, 34 and 35 is a scraperblade 71 carried by brackets 72 made fast to appropriate ones of thetransverse beams of the upright frame, and these scraper blades arearranged to engage the respective rollers at points a' short distancebelow the points of close approach of the rollers.

The brackets 72 carry shelves 73 and 74 on opposite sides of the uprightcenter line passing between the respective pairs of roll- Each shelf 73is appropriately bent and terminates in a convexly curved edge 75 andeach shelf 74 terminates in a convexly curved edge 76, both shelvesbeing more or less pendently arranged with the end 76 of the shelf 74lower than the end 75 of the shelf 7 3, and these curved edges aredisposed on relatively opposite sides of an upright center planeextending between the approaching faces of the sets or pairs of rollers.The purposes of these structures will appear hereinafter.

Each shaft 68 is extended beyond the same side of the upright frame asis .the shaft 7 where carrying the pulleys 8 and 9. The shaft 7 has asprocket wheel 7 7 mounted thereon and the shafts 68 have each asprocket weel 78 mounted thereon. Extending about the sprocket wheel 77is a sprocket chain 79 also carried about the sprocket wheels 78 on theshafts 68 beneath the rollers 31, 32 and 33, the course of the chainbeing such that the brushes 67 have those portions engaging the screens69 there moving downwardly.

In order that the course of the chain 79 may be properly directed it isalso carried about an idler sprocket wheel 80 appropriately located todirect the return run of the chain 7 9 after passing about the statedsprocket wheels 78.

Mounted on the brush shaft 68 beneath the roller 34 is another sprocketwheel 81 about which there extends a sprocket chain 82 carried about thesprocket wheel 78 on the brush shaft 68 under the roller 35.

Garried by the brace 6 is another flour bin 83 supported by hangers 84and underridden by a brush like the brushes 67, such brush beingsupported upon a shaft 85 carrying a sprocket wheel 86 about whlch thesprocket chain 82 is directed. The bin 83 has its lower discharge endcovered by wire cloth or other screen 87 so that the brush beneath itacts in the same manner with respect to the flour within the bin 83 asdo thebrushes 67 with respect to flour within the bins 61. The bin 83 isso situated as to override that portion of the apron 48 just after itleaves the supporting roller 48 and before it reaches the supportingroller 51.

Beneath the pair of rollers 33 and 36 and above the apron 49 wheremoving below said rollers are two adjacent shafts 87, 88, suit ablyjournaled in cross pieces 2 of the up-' right frame. These shafts carrycoaeting cutter wheels 89 in suitably spaced relation, and the shaftsare connected for rotation in opposite directions by gear wheels 90, 81,respectively. The shaft 88 is continued at one end beyond the frame andthere carries a sprocket wheel 92 connected by a chain 93 to anothersprocket wheel 94 on the shaft 30 carrying the roller 36, whereby motionis imparted to the trimming cutters 89.

Extending about an elongated directionchanging roller 95 mounted in theupright frame beneath the shafts 87 and 88 are aprons 96 each having onerun extended about another direction-changing roller 97 mounted on oneside of the upright frame, while the other runs of these apronsarecarried about the roller 46, and ultimately reach the roller 53 andtravel in the same direction as the apron 49.

The shaft 44 at the end remote from the friction wheel 47 projects asuitable dis tance beyond the upright frame and there carries a sprocketwheel 98 connected by a sprocket chain 99 to another sprocket wheel 100on a shaft 101 mounted in standards 102 in which also the supportingroller 51 is mounted.

The sprocket wheel 100 is mounted to turn freely on the shaft 101beingheld against longitudinal movement thereon by suitable collars 103or in any other appropriate manher. to and spaced from an internal gearwheel 104 by connecting studs 105. The gear wheel 104 may also bemounted upon the shaft 101 to turn loosely thereon, while concentricwith the gear wheel 104 is another gear u wheel. 106 made fast to theshaft 101. Tnterposed between the gear wheel 104 and the gear wheel 106is a pinion 107, whereby mo- The sprocket wheel 100 is made fast w tionis transmitted from the gear wheel 104 to the gear wheel 106. The pinion107 is mounted on a stud 108 carried by a bracket 109 inturn carried byan appropriate one of the beams 3.

Mounted on the shaft 101 so as to turn therewith is a roller 110 incoactive relation to the roller 51, and between the rollers 51 and 110the upper run of the apron 49- travels. I

Carried by-the peripheral portion of the roller 110 longitudinallythereof is a dough cuttin blade 111 projecting radially from the re ler110, so as to reach or approxlv mately reach the apron 49 across thespace separating the surface of the rollers 51 and 110.

Hinged to uprights 1 of the upright frame ate notches without liabilityof escape therefrom, said notches serving as ports for the mandrel 116.

The shelf 113 is carried near the end remote from the hinge 112 by alink 120 pivoted at one end to one of the cross bars 2 journal supnearthe top of the upright frame, and at the other end provided with aseries of per forations 121, any one of which may be traversed by oneend of a rod 122 carried by the shelf 113 and a cotter pin 123 or othersuitable device may serve to hold the link 120 to the rod 122.

In preparing the machine for forming the dough sheets, the dough,indicated at 124, is first rolled out into relatively thick sheets,

. and then wrapped about the mandrel 116 to be then placed upon theshelf 113.

The end of the dough sheet 124 is intro-- duced between the upper pairof rollers 31, 34, and it being assumedthat .the machine is in operationand that flour is deposited in the several bins 61 and the bin 83, the

dough sheet travels between the rollers '31 and 34 being there reducedin thiclmess. After-passing between the rollers 31 and 34 the thinneddough sheet first comes in contact with the end of the shelf 73, wherebyits course of travel is deflected to one side of the upright center lineof travel and then the dough sheet reaches the curved edge 75 of theshelf 74, whereby the travel of the sheet .is deflected in the oppositedirection and to the other side of the upright center line. supported bythe two shelves 73 and 74 deflecting its course of travel in oppositedirections, then reaches the rollers 32 and 35, being at such pointstill further reduced in thiclmess. The dough sheet now reaches thesecond set of shelves 73 and 74 after passing which the sheet is finallysubjected to a still further thinning by theaction of the pairs ofrollers 33 and 36, theselast named rollers The dough sheet thus in partyreducing the dough sheet to the desired thinness. lmmedlately afterpassing the tween the pairs of cutters 89 whereby the.

rollers 33 and 36 the dough sheet passes beedges are trimmed and thesheet is brought 70 to an even width. After the trimming the dough sheetis directed upon the up-traveling run of the apron 49 on its passagetoward the roller 48 and ultimately the sheet is carried by the apronbetween the rollers 51 and 110 where at intervals the dough sheet issubjected to the action of the cutting blade 111, whereby the sheet isperiodically severed into appropriate length-s, one such severing outbeing indicated at 125 in Fig. 1 above the table 48.

Each section of the dough sheet as cut is removed from the apron 49 to abaking machine, such as shown and described in the aforesaid reissuedLetters Patent. A convenient means for facilitating the removal of thesevered sheet is shown separately in Fig. 7. There is provided a roller126 with studs 127 thereon, and this roller. is carried by a frame 128having a manipulating handle 129. By applying the studs 127 to one endof the severed sheet it is readily rolled upon the roller 126 andtransported to the baking machine.

In order to prevent the dough from sticking to the rollers flour isdeposited upon the traveling dough sheet from time to time. This isaccomplished by the brushes 67 which are rotated so that their bristletufts 70 travel'across the screens 69, and catching in the flour therebydistributed the latter is directed toward the traveling dough sheet asit approaches the next pair of thinning rollers. To further control thedirecting of the flour against the sheet, each spout 62 has a projectinlip 130 below the respective brush 67, where y the flour projected bythe brush is directed on to the next lower roller and toward thetraveling dough sheet. The scrapers 71 acting on the respective doughthinning rollers scrape off any dough that may strick thereto and soprevent accumulations of dough which might cause subsequent portions ofthe dough sheet to adhere to the rollers. The bin 83 is so located thatflour is dusted on the dough sheet just before reaching the roller '110,and thereby preventing adhesion of the dough sheet to tacle 131 may belocated in convenient position to receive such trimmings.

More or less flour finds lodgment on theapron or belt'49 and to collectsuch flour which is liable to drop from the lower run of the apron inits return to the drum 46,

a chute 132 is mounted in the frame of the machine underneath the lowerrun of the apron, and this chute may be tilted so that its lower endwill discharge into the receptacle 131.

In the arrangement shown in the drawings the chain 99 drives thesprocket wheel 100 in a direction which if the cutter 111 were driven inthe same direction would cause it to move oppositely to the direction oftravel of the dough sheet, wherefore the gearing 1, 106 and 107 isprovided to effect a change of direction of rotation of the cutter 111,so that it coincides in direction of travel with that of the dough sheetupon the apron 49.

Since in its passage through the machine the dough sheet isprogressively thinned it becomes correspondingly elongated over itslength as rolled upon the mandrel or drum 116. For this reason the doughsheet must travel progressively faster as it passes through the machine,and, therefore, the driving means for the pair of rollers 32 and 35 isarranged to cause a higher speed of rotation of these rollers than ofthe pair of rollers 31 and 34, while the pair of rollers 33 and 36 havestill'a higher rate of rotation. The parts are so proportioned thatthese diiferent rates of rotation all agree with the rate of travel ofthe dough sheet throughthe machine, and its progressive increase inspeed as it is thinned out.

.It'is not necessary that friction drive be employed for causing therotation of the rollers 31, to 36, since the shaft 14 may carry bevelpinions 17 18 19 and 20*, engaging corresponding bevel pinions 39, 40 41and 47*, all as shown in Fig. 9, and re- 40 placing the friction drivebest shown in Fig. 3, it being understood that the various intermeshingbevel pinions are properly proportioned to bring about the desiredvariations in speed. Again, a sprocket drive such 4 as indicated in Fig.8 may be used to replace either the friction or the gear drive of Figs.

3 or 9. In this event the shaft 7 carries intermeshing gears 7 7 btransmitting motion from the shaft 7 to a gear 10 on a shaft 12 on whichis mounted a s rocket wheel "13,

which latter by means 0 a sprocket chain 14 imparts motion-to a sprocketwheel 39 mounted on the shaft 25, and the latter carries anothersprocket wheel 25*, which by a means of another sprocket chain 14*transmits motion to still another sprocket wheel 40 mounted on the shaft26. Also mounted on the shaft 26 is another sprocket wheel 7 26transmitting motion by means of a chain 1 1 to a sprocket wheel 4:1 onthe shaft 27, while a sprocket wheel 27 on the shaft 27 transmits motionby a chain 14 to a sprocket wheel 41:7 on the shaft 44. By the sprocketarrangement just described wherein the parts are assumed to be properlyproportioned,

motion is imparted to the various parts to be driven in the same manneras in the structure of Fig. 3.

By these showings it is evident that the invention is not limited to anyparticular mode of transmitting motion, so long as the functionsperformed by the driven parts are attained.
